Prepare your formula by buttons at the top app section and then press on 'y' or touch drawing zone.   Once a formula was entered, It's possible to enter a value instead of x variable, the result is computed and if the position of calculated point is inside of drawing boundary, it would appear.

  Units number of the chart section is changeable. By default, it is set to 20.  Enter a value between 5 to 80. For more details and accuracy try small numbers but for more result to view enter great numbers, after editing the unit's number.   

Axes are displaceable.

There are four slots at bottom app section that keep formulas for further usage.
